PAGKER FINGER FOR SIGNATURE-DELIVERY MECHANISM.

Application filed November 9, 1923. Serial No. 673,?74.

It has heretofore been diificult, if not impossible, to deliver, free from smut and offset, signatures of the better grades of magazine printing into what is known in the trade as packer deliveries, because of the .Xtendcd contact of the fingers with the freshly printed signatures.

The object of my invention is to eliminate these objectionable features of this type of delivery by providing a novel type of pack er fingers which can be used to carry the signatures into the packers with the minimum amount of disturbance, said fingers being provided at their signature engaging face or faces with a multiplicity of points for engaging the printed portion of the signatures and also being provided with upper and lower margin engaging members, the upper margin engaging members being com posed of non-metallic material, such for instance as wood fibre, so as to eliminate all tendency of the upper free edges of the signatures to cling or stick to the fingers on their return stroke and thus get in the way of a succeeding signature and cause a choke at this point in the delivery.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents in top plan so much of a packer delivery mechanism as includes th novel improved packer fingers.

Fig. 2 represents a face view of the same, the finger supporting slide being shown in section.

Fig. 3 represents an end View with the linger supporting slide shown in section.

Fig. t represents a cross section on an en larged scale, taken in the plane of the line IVIV of Fig, 3.

The packer finger supporting slide is denoted by 1, to which slide the packer fingers 2 are secured in the usual manner by bolts The opposite signature engaging faces of each of the packer fingers are serrated, as shown at 4: to form a multiplicity of points arranged to engage the printed portion of the signatures.

The packer fingers are also provided on their signature engaging faces with upper and lower margin engaging members 5 and 6 respectively. A separate upper margin engaging member being provided for each face of the packer finger while a common lower margin engaging member is provided for the corresponding faces of the plurality of fingers The upper margin engaging members 0 material, such for instance as wood fibre, so that the free edges of the signatures will not cling or stick to these members on the return stroke of the fingers. These upper ma-rgln engaging members 5 are removably secured in position by the screws 7.

The cross bars which form the lower margln engaging members are removably secured to the packer fingers by the screws 8.

These upper and lower margin engaging members project beyond the planes of the points so as to take the bulk of the pressure on the unprinted top and bottom margins of the signatures thereby, together with the provision of a multiplicity of points on the faces of the fingers which engage the printed portion of the signatures, serving to permit the delivery of the signatures into the packer without offset or smut. This renders the packer delivery suitable for handling high class work in a successful manner.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is 1. A packer finger having a signature en gaging face serrated to form a multiplicity of points arranged to engage the printed portion of the signature.

2. A packer finger having opposite signature engaging faces serrated to form a multiplicity of points arranged to engage the printed portions of the signatures,

3. A packer finger having its signature engaging face provided with a multiplicity are composed of non-metallic of points and upper and lower margin engaging members.

4:. A packer finger having 1ts signature engaging face provided w1th a multiplicity of points and upper and lower margin engaging members projecting beyond the plane of said points.

5. A packer finger having its signature engaging face provided with a multiplicity of points and upper and lower margin engaging members, the upper margin engaging member being composed of non-met-allic material.

6. A packer finger having its signature engaging face provided with amultiplicity of points and upper and lower margin engaging members, the upper margin engaging member being composed of wood fibre.

7. A packer finger having its opposite signature engaging faces provided with a multiplicity of points and upper and lower margin engaging members.

8, A packer finger having its opposite signature engaging faces provided with a multiplicity of points and upper and lower margin engaging members projecting be yond the planes of said points.

9. A packer finger having its opposite signature engaging faces provided with a multiplicity of points and upper and lower margin engaging members, the upper mar gin engaging members being composed of non-metallic material.

10. A packer finger having its opposite signature engaging faces provided with a multiplicity of points and upper and lower margin engaging members, the upper margin engaging members being composed of wood fibre.

11. A suit-able support, a plurality of packer fingers uprising therefrom, the sig nature engaging face of each finger being provided with a multiplicity of points, separate upper margin engaging members for said fingers and a common lower margin engaging member for said fingers.

In testimony that I claim the foregoing as my invention, I have signed my name this 7th day of November, 1923.

HOWARD M. BARBER.
